TETHER.

SPECIFICATION forming part of Letters Patent No. 390,808, dated October9,1888.

Application filed July 10, 1888. Serial No. 279,599.

To all whom t may concern.-

Beit known that I, GEORGE S. SERGnAN'r, of Greensborough, in the countyof Guilford and State of North Carolina, have invented a new and usefulImprovement in Tethers, of which the following is a specification.

My invention is an improvementin tethers; and it comprises a standard orstake, a bracket or carrier supported thereon so that it may rotate onor be adjusted along said stake, a pole, and a springconnection whichsupports the pole and serves as the connection between the said pole andthe bracket or carrier of said pole.

The invention consists in the novel constructions and combinations ofparts, as will be hereinafter described and claimed.

In the drawings, Figure I shows the invention as in use. Fig. 2 is adetail sectional elevation of a part of the device. Fig. 3 is asectional view on about line x x, Fig. 2. Fig. 4 is a detail view of thebracket, and Fig. 5 illustrates the construction employed when a coiledspring is used.

The stake or standard A maybe of any suitable length, and is, inpractice, ordinarily driven in the ground, as will be understood fromFig. l. On this stake I fit the bracket or carrier B, which has eyes bbformed with openings to receive the stake, so that the bracket may turnon or be adj usted up or down on the stake. These eyes b I) are rigidlyconnected together by the body of the bracket, which body unites thesaid eyes at one side; but the said eyes are arranged sufficiently apartto form a recess or opening fitted to receive the collar O, which isprovided with a clampscrew, c, and serves to secure the bracket in anysuitable vertical adjustment on the stake, the collar fitting betweenthe eyes and serving t0 prevent any movement of the bracket up or down,and yet forming no obstruction to the turning of the bracket on thestake, as desired.

By arranging the collar between two eyes of.

the bracket a single collar suffices to' secure the bracket frommovement either up or down on the stake, and when the collar is releasedby loosening the clamp-screw it may be adjusted up or down by thecorresponding movement ofthe bracket. The bracket also has an arm,

B', which in the construction shown projects outward and upward at anincline and serves to receive the spring D. By preference this (Nomodel.)

arm B has a curved or inclined bearing-sun face, b, which serves to easeor make gradual the bending of the spring, and thus avoid the abruptbending of same and the consequent danger of breaking resulting fromsuch abrupt bending.

The spring I) may be formed of a tlat plate, or, preferably, a pluralityof such plates titted face to face, as shown in Figs. l and 2, the saidplates being secured at one end to the bracket or carrier and at theirouter ends to thepole E. The pole E also has a rounded or inclinedbearing-surface, e', similar to the surface b', and for a similarpurpose-namely, to prevent the abruptbending of the spring. In theconstruction shown in Fig. 5 the said surface c is formed on asocket-piece secured to the pole.

It will be understood that where desired a coil-spring, as shown in Fig.5, may be used, such spring being provided at its ends with stems orShanks fitted and secured in suitable sockets or openings provided onthe carrier or bracket and on the pole. As stated above, the dat plateor plates may be preferred.

The bolts F, for securing the springs to the pole,have their heads felongated laterally and Vformed to brace the pole, to prevent anysplitting of same.

In use the tethering-rope may be secured to the outer end of the pole,as will be understood from Fig. l.

The construction is simple, inexpensive, can be easily adjusted for use,and possesses no parts likely to be easily broken or to get out oforder.

Having thus described my invention, what I claim as new is* I.V Animproved tether comprising the pole, the bracket or carrier, and thespring extended between and fixed to said bracket and, pole, a bearingbeing provided for the spring adjacentits end or ends, such bearingbeing rounded or inclined in the direction of length of the spring,substantially asset forth.

2. In atether, the combination of the bracket or carrier having arounded or inclined surface, b, the pole having rounded or inclinedsurface e', and the spring extended between and xed to both the bracketand the pole, substantially as set forth.

3. The herein-described improved tether,

IOO

comprising the stake, the bracket jonrnaled and revolving on the saidstake, a spring having one end xed rigidly to thebrack et, whereby itmay support the pole on its opposite or outer end, and whereby the saidspring may turn or move around the stake, and the pole secured to andsupported on the outer end of the spring, substantially as set forth.

4. The improvement in tethers consisting of the stake, the bracketprovided with eyes perforated to lit on the stake and separatedi'roineaeh other, the collar fitted and secured on the stake between theeyes of the bracket, such collar being formed to it snugly between theeyes ofthe bracket, whereby to preventsaid bracket from moving u p ordown on the stake, the pole, and connections, substantially as setforth.

5. The improved tether comprising the bracket, a spring consisting of anumber of flat spring-plate strips held at one end to the bracket, andthe pole held at its inner end to and supported on the outer ends of thesaid strips, substantially as set forth.

6. The improved tether herein described, consisting of the stake, thebracket having eyes separated to receive the fastening-collar betweenthem and perforated for the passage of the stake, such bracket having alateral arm curved on its upper side, the fasteningeollar, the polehaving its innerend curved onits upper side, and the spring secured tosaid bracket and pole, substantially as set forth.

7. As an im provementin tethers, the bracket having bearings or openingsby which it may be jourualed on the stake, and provided with a lateralarm, the spring fixed at its inner end rigidly to the said lateral arm,and the pole supported on the outer end 0f the spring, all substantiallyas set l'orth.
